Release Notes
March 2019
These release notes provide information about the LiteSpeed for SQL Server release.
Topics:
LiteSpeed for SQL Server, or LiteSpeed, is a fast and flexible backup and recovery solution that allows DBAs to easily maintain complete control over the backup and recovery process. Its low-impact, high-performance compression and encryption technology enables users to reduce storage costs and protect data, while improving both backup and disaster recovery times. With the improved compression and LiteSpeed's Fast Compression technology, LiteSpeed for SQL Server can further reduce disk space and backup time up to another 85% over traditional, compressed full backup solutions. The result is a unique backup and recovery approach, unmatched in flexibility, that greatly reduces backup times, creates a significantly smaller storage footprint, and maintains a high level of recoverability.
Store database backups directly into the following cloud platforms: Microsoft Azure Blob storage, Amazon S3 and Google Storage.
Automate backup testing and running database consistency checks using Automated Restore
